TO ALLWHOM IT MAY CONCIEIRN:v

Be it known that I, CHARLES VAN DE MARK, of Phelps, in the county of Ontario, and State-of yNew York,

have invented an Improved Cooking-Stove; and Ido hereby declare that the following is a full and exact description thereof, reference beinghad'to the accompanying drawings, making part of, this specification- Figure 1 being a horizontal section, justv below the top plate, of a cooking-stove constructed with my improvements.' I i l Y Figure 2, a vertical section thereof, in a planeY indicated by a line, zum, gfl.

Figure 3, a vertical section of the same, in a plane indicated by aline, y y, lig. 1.

Like letters designate corresponding parts in'all of' the figures.

My improvements are intended for the'purpose of concentrating the heat around one or more boilers, or for distributing it, either equally or nnequally, as may ybe desired, in diierent places, whereby much fuel and time may be saved in cooking and heating, and' .the heat may be controlled more eilicientlythan with stoves heretofore in use.

In the drawings, let represent. the fire-chamber of afcooking-stove, B the heating-chamber, back ot the Y lire-chamber, and C the oven. With-tho exception of the parts which I' claim as novel, thestove maybe constructed in any suitable or desired manner. i Between the fire-chamber A and heating-chamber B, I'make a partition, G, across the whole width of thejstove, -by Vwhich the passage for thedraught and products of combustion ,is closed, exceptbywnlvesjor dampershft, z'z, two of them, h h', being in they upper part, and the two, 1.' z', in the lower part of the partition, as'most clearly represented in iig.l 3.l The upper valycs h h are shown as sliding in and out, and controlled by slide-:rodsm 7n, andthe lower valves are shown vas swinging up on rods n 1t, to close the apertures, and down towardthe'rearofthe stove to open them. But the lower valves might slide, instead of swinging, or the upper valvesmight swing. The arrangement shown, however', isfb'est and most convenient, since, by having the upper valvesfslide,vthey do not interfere with those below-,and having the lower valves swing, the h eat can be directed more or less upward. against the boilers, 'overthe heating-chamber B, as indicated by oneposition. of ther-ed lines' in iig. But I do not confine myself to any particular construction or arrangement o f'valve's,mortoany' particular.number, thong-htivoofftthfilpper:andtwo 'of .the lower valves,l lin ordinary stoves, with two b'oiler-holesin'the front part and tw'oin the back part,1'11a'ybe` considered the most yconvenient and suitable.v If there is onlyvone boiler-hole in the front of the stove, there will be but one setot` the valves, or but one upper valve h or, if there werefmore than two boiler-holes in front, there would be as many upper valves h h, or as many sets of valves'h z', as boiler-holes. y Between the upper and lower valves, I extend a horizontal division-plate, D, forward from the partition Gr,- under each boiler-hole. b, over the lirechamber, extending i'ar enough beyond said boiler-hole, all around the front and sides, to furnish space around Athe boiler, when inserted, to allow suilioient circulation of the draught around 4the same, as indicated by arrows in iig. 1. This lu`e-space above the division-plate D is enclosed'by a band or side plate, E,`eizcept a portion at the innel` back part, where a flue-opening, a, is left to allow the products of combustion to arise and enter the flue-space from the iire-charnbei` underneath. This flue-opening is separated from the upper valve by a partition,

Il, extending from the partition Gr forward to the boilehole,'so that', when the boiler is inserted, the draught or products of combustion will have to pass all around it from the flue-opening to the valve. Directly under each boiler-opcnng b, in Vthe upper part of the stove, is another boiler-opening c, in the division-plate D, properly a little smaller in diameter, as shown; and the boiler I, fig. 2, is intended to reach down through both openings, b c, and iit them both, substantially as represented, reaching but a little distance below the division-plate D. Thus, when it is'desred to concentrate vthe heat aroundonc boiler, all the valves-in the partition G may be closed, except the upper valve adjacgnt to 4that boiler. y'.lhen it will have not only the direct heat of the lire against its bottom, but the entire draught of the lire turned around its periphery, in the due-space above the" division-plate, so that cooking or heating'can be done in the boiler very rapidly and economically; or, on the other hand, if only a gentle heat is wanted against'one boiler, its upper valve isclosed, so that only the direct heat against its bottom acts on it, while the draught may be drawn through other valvees'paces. Or, again, the

different valves maybe opened, more or less, and so divide the draught, either equally or uncqually, among the different boilers, as may he required, and tle draught may either pass entirely through the upper lvalve-spaces, or entirely through the lower ones.

What I claim as my invention, and desire to secure by Letters Potent, is'

The partition-plate G, between the fire-chamber A and heating-chamber B, provided with one or more upper and one or more under valves 7L 7L and z' z', substantially as and for the purpose herein spcciied.

I-:Llso claim the boilerl1ole plate or plates D, and enclosing side pla-te or plates E, arranged in combi`v nation with partitionlvolves h z', so that' the heat may be directed against the bottom part of a boiler or boilers, I, only, or both against the bottom and :ironnd the sides thereof, substantially as and for the purposes herein specified. i
